0 0

Step-by-step explanation:

<em>"Of the following dotplots, which best represents the possible results from the simulation described?"</em>

The sample size is 100, and the probability of success is 0.015, so the expected value is 1.5.  Meaning we would expect a dotplot with most of the dots at 1 and 2.

A cylindrical water tank has a diameter of 5.3 meters and a height of 9 meters. What is the maximum volume that the water tank c
atroni [7]

Answer:

198.56m^{3

Step-by-step explanation:

To find the volume of a cylinder, you need to find the area of the cross-section (one of the circles on the side) and multiply it by the length.

Area of the circle = πr^{2} = π x (5.3/2) x (5.3/2) = π x 2.65 x 2.65 = 7.0225π

Volume of the cylinder = 7.0225π x 9 = 63.2025π = 198.56m^{3

We need to subtract:  the scientist needed 57,500 dollars, but already had 32,506, so we need to find what's left: 57,500 - 32,506 = 24,992 dollars

Your answer is A.  Hope that helps! :)

Answer:

y =-3000x +12000

Step-by-step explanation:

answer is

1)   12000 is the constant therefore when the number of hours is 0 the tickets are 12000

2)  the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000  (negative because it is reducing)
